Application filed February 6, 1925.,-Sfi1'l2ll No. 7,280.

This invention relates to, Winding machines and more especially to improvements in the general type of machine disclosed in. my copending application, Serial No. 668592 filed January 25, 1924: on winding machines. it is an object of my invention to provide a machine adapted to operate simultaneously aplurality of spindles from a common drive mechanism, each spindle forming a portion oil a separately mountable spindle unit which includes all of the elements essential to a separate Winding; machine, the spindle itself, operative connecting means between the spindle and the common drive mechanism, a traversible thread guide and traversing means therefor and suitable stop devices.

it is a further object of my invention to provide an improvedtype ot' traverse mechanism which is driven directly from the spindle shaft. This insures a proper ratio of spindle rotation speed to guide traverse speed. Additionally it does away with the necessity of the rock shafts, rock shalt opermechanisms,the traverse arm clutches and clutch throw-out mechanism.

Other objects of my invention will appear in the following specification and claims and will be disclosed in the accompanying dravvin Which-- Figure l is a side elevation of one of my Winding heads; H I

The frame 1 has mounted therein in suitable bearings 2 a shaft 3 adapted to be rotated by any suitable means. Fixedly se cured to the'shatt are a plurality of trie tion drive Wheels l; each of which is adapted to engage friction disks 5 to drive a pair of opposet, ly mounted spindles 6.

The spindle 6 is screu threadedly secured iuthe end ot a spindle shatt 'i". which is rotatably mounted in su table fr ction reducing bearings 8 in an auxiliary frame member or bracket 9 detachably secured by bolts 10 to the frame 1.. The spindle shaft is securedagainst endwise movement by collars 11 and 12 fixed thereto and abutting the bearings 8.

Fixedly secured on the shaft 7 is a WOIIII sleeve 13 having a four thread worm 14 cut in its outer surface; The TOIWEtl'dBIlCl 15 of the worm is ota reduced diameter to pro vide an abutment or shoulder 16. The for- Ward end 15 of the Worm sleeve is cut away into substantially semi-cylindrical {01111 to enable it to have driving engagement WYltll a similarly cut portion 17 ot a sleeve 18 rotatably mounted on the shaft. The "friction disk 5 is fixedly secured to the sleeve 18. Loosely mounted on the sleeve .18. is a compression s rine 1.9 havingone end abutting the disk 5. This springiorces the disk 5 into driving engagement with the driving Wheel 4 to rotatethe spindle.

A brake lever20is pivotally mounted on the bracket 9 by means of a stud 21. The upper arm 22 ot'the lever 20 is torn ied to re ceive av brake 23 of some suitable material such as fiber or rubber. The other arm Q l ot' the lever 20 has a portion which extends horizontally in a direction substantially parallel to the spindle. ii te nsion spring 25 of greater strength than the spring; 19 is secured at one of its ends to the rear-iv rd end of the arm 24 and-at its other end to a suit able stud 26 fixed in the bracket. A flange 27 on the arm 24 is adaptedto be engaged by an arm 28' which is fixed on an operating control rod'29. The control rod 29 is rotatably mounted in the bracket 9 at 30 and 81 and is limited against endivise movement by the set collars 32 and Fixedly secured to the operating. control rod 29 is a collar 34-. to which is fixed an arm 235. Sn the rearward end oft the rod a suitable handle 36. A stop control rod 37 is longitudinally slidably mounted in bear ings 88 and 39 of the bracket and in a bear ing 40 in an auxiliarybracket 41 secured to the bracket.

A collar 4:2 is by means (it a set screw :2 nressiou spring; mounted het bearing 38 and the collar 4-2 tend the rod 37' the rod is handle. 38

torivard. Forward movement; (it limited by a inn isturneu in a countcra u cliv ill) 'which straddles the traverse rod 70.

direction the arm 35 is moved out of the path of the collar 42 and the rod 37 moves forward under the influence of the spring43 until its forward motion is arrested by pin 44. Rotation of the rod 29 also raises the arm 28, lifts the arm 24 against the action of spring 25, and moves the brake 23 out of contact with the disk 5 thus permitting the spring 19 to force the disk into driving engagement with wheel 4 and putting the spindle into rotation.

en rotative pressure is now released on the handle 36 the rod 29, under the influence of the spring 25 acting through arm' 24, flange 27, and arm 28, tends to rotate in a clockwise direction.

The collar 42 has now moved under the arm and the arm 35 will rest on the said collar until'the rod 37 is movedbackward.

The'sp'indle thus continues to engage operatively the wheel 4 until the rod 37 is moved backward.

Slightly ahead of the collar 42 on the rod 37 another collar 45 is fixed by set screw 46. Fixed to this collar is a forked armn47 1e rod 70 is adapted to be reciprocated by means hereinafter to'be described and slides in bearings 71 and 72 of the bracket and auxiliary bracket. The arm 47 has a i flanged portion 48 which'serves to limit the lars and 56 fixedly secured thereto.

downward motion of an arm 49. the up wardmotion of said arm being limited by the traverse bar 70.

Fixed on the traverse bar 70 is a collar 75 which, in the backward movement of the traverse rod, does not quite reach the arm 47 and so does notv move the rod 37 backward. The arm 49 has a turned over or flanged end 50 of such length that when this flange is moved into the path of the collar 73 the arm 47 and rod 37 will be moved, by the traverse rod, backward to such a degree that the arm 35, under the influence of spring 25, falls in. front of the collar 42. This clockwise rotation of rod 29 permits the spring 25 to act on the brake lever 20 pushing the brake against the disk 5, forcing the same out of contact with the wheel 4 and simultaneously braking the said disk.

A stop rod 51 is rotatably mounted in sui able bearings 52, 53 and 54 in the bracket and is limited in eudwise movement by Q0]- The arm 49. heretofore discussed is fixed to the collar 56 and oscillates therewith. Between the collar 56 and the bearing 53 a collar, 57 isrotatably mounted on rod 51. Fixedto collar 57 is a thread arm 58 having a flexible extension 59 and an eyelet 60. The thread arm is additionally provided with a forked portion 61 which straddles a horizontally extending bent portion 62 ot the arm 49. The t'orl-red portion loosely engages the arm portion 62 so that oscillation of arm is noted that the thread is fed to the spindle from above. The thread )asses through the eyelet on its way to tie thread guide 63 and it will be seen that the draft on the thread thus tends to hold the arm extension 59 up. This results in the forked portion 61 being moved downwardly thus. through arm portion 62, rotating arm 49 and moving flange 50 out of the path of the collar 73 thus permitting the winding to proceed. If the thread being wound to this spindle breaks the extension 59 will fall and the flange 50 will be moved into the path of the collar 73 stopping the machine.

The thread guide 63 is mounted on a yoke 64 slidably and rotatably mounted by means of sleeves 65 on the screw-threaded portion 74 ot the traverse rod 70. Between the sleeves 65 a sleeve 66, to which the progression or contact wheel 67 is fixedly secured, is also mounted on the rod portion 74-. This last named sleeve has a sliding lit with the thread rod andhas cutaway portion through which a portion of an arm 68 is adapted to extend to engage the threaded rod as a single toothed gear. The arm (38 is pivotally secured to the wheel (37 and is spring-pressed into engagement with the threaded rod by bent leaf spring (39. This permits of the free movement of the guide in either direction along the threaded rod with out rotation of the wheel as in setting the guide preparatory to winding. Rotation of the wheel by contact with the yarn being wound causes the guide to be moved along the rod. An arm 64 is mounted on the threaded rod and has a forked portion 64" following the rod 51 and a portion 64" adapted to act as a limit to rotation of the yoke away from the spindle.

The winding may be stopped manually at any time by rasping any portion of the rod 37 and moving it backward. The rod is additionally provided with a stop arm 37 adjustably mounted on the rod 37 which ends to a point in proximity to the threaded rod and is adapted to be en aged by the sleeve 65 to move the rod 37 backward when the winding has progressed to the desired length.

The traverse rod 70 is secured by a link to a traverse arm 76 pivoted at 76 to a stud 77 secured to the frame. Substantially midway of its length the arm 76 is provided with a cam follower 78 adapted to follow in cam slot 79 formed in the face of a cam block 80 rotatably mounted in a suitable bearing 81 in the frame. A portion of the surface of the cam block is formed to provide a worm gear 82 adapted to-mesh with and be driven by the worm 14. The ratio between the worm and the worm gear may be any that is desired but I have so delid signed my four thread Worm and worm gear that there Will be thirteen revolutions of the spindle to each complete revolution of the cam block or siX and onehalf revolutions to every throw of the traverse rod.

The operation of my device has been explained in detail as the disclosure progressed and, it is believed, Will be clearly understood by those skilled in the art.
